Share|OTTAWA - A tearful Mohamed Harkat and his wife Sophie vowed Friday to press on with their marathon legal fight following a Federal Court ruling that declared the Ottawa man a threat to Canadian security. Harkat told a news conference he was shaken by the decision, which brings him a significant step closer to deportation to his native Algeria. He plans to appeal.

"I can't sleep. I'm not thinking straight, I have pain in my stomach," said Harkat, repeatedly dabbing at his eyes during the emotional session. Harkat, a former gas station attendant and pizza delivery man, was arrested eight years ago Friday under a national security certificate on suspicion of being an al-Qaida sleeper agent. He denies any involvement in terrorism. Flanked by Harkat's lawyers and a clutch of supporters, Sophie called the ruling a "punch in the guts that will leave marks" for a long time.
